Unfortunately, the internet offers only confusion on this issue. GreTsch of course aren't going to brag about it if they do, and there are differing opinions everywhere you go. To tell you the truth, I don't care, if it sounds good and Keller OR Gretsch made it, so be it, I'm cool with that. I'm a Ludwig guy, but I also have and have had some Gretsch stuff and I love it.
But that aside, Keller makes a great product but it is only the base of what makes a drum great. All the other subtleties are also important to the tone of the drum.
ie: The finish, whether it be a pearl or woodgrain, Hardware and it's placement on the shell, How MUCH hardware (will the tom mount suck the life right out of it) and all the other things that make a raw shell into a drum.
